Ambient Operating
Conditions
Temperature: -40 to 66C (-40 to 150F) when using 0–10 VDC outputs;
-40 to 40C (-40 to 104F) when using 4–20 mA outputs
Humidity: Up to 95% RH non-condensing; Maximum Dew Point 29C (85F)
Ambient Shipping and
Storage Conditions
Temperature: -40 to 80C (-40 to 176F)
Humidity: Up to 95% RH non-condensing; Maximum Dew Point 29C (85F)
Analog Output Voltage Mode (0–10 VDC):
10 VDC maximum output voltage
10 mA maximum output current
Requires an external load of 1,000 ohms or more
The AO operates in Voltage Mode when connected to devices with impedance greater than
1,000 ohms. Devices that fall below 1,000 ohms may not operate as intended with Voltage
Mode applications.
Current Mode (4–20 mA):
Requires an external load between 0–300 ohms
The AO operates in Current Mode when connected to devices with impedance less than
300 ohms. Devices that rise above 300 ohms may not operate as intended with Current Mode
applications.
